YES !!!! Re: Gray balance approach reasonable? (snibgo)

WOOHOO! Holy smokes, thank you so much for all your help snibgo. It was a bit of a steeple chase fixing the compile errors and the changes in MagickCore function calls from V6.9x to V7.0x, but I am so grateful for your guidance, and happy with myself at not having given up in the face of "yet anothe...

Re: Gray balance approach reasonable? (snibgo)

Looks even better, as I would expect! And gives me the confidence that the effort I put into copying your CygWin implementation will really pay off.

Thanks for the reply! I concur with your speculations. Fortunately for my current need, I don't need to worry about the complete range of subjects. I too thought about those times when something is visible in IR (Sun setting through forest fire smoke) but not in the normal camera, the transform fall...

Gray balance approach reasonable? (snibgo)

Hi there. I would appreciate some advice/direction: I would like to transform the color balance from a sensor with "no IR-filter" (Canon 60Da) to a "normal" one, say Canon 5DMark I. I have written up a web page describing the problem and a potential solution, including a couple of images: https://si...
